Having already organised a home from home in Edinburgh, they are also calling on all fans to send messages of support to Michael Cheika's squad ahead of Saturday's Heineken Cup final against Leicester Tigers.
'Backing The Boys' is just one of the OLSC initiatives to show the Leinster squad just how many fans will be behind them at Murrayfield on Saturday.
Send your e-mails to: firstname.lastname@example.org with 'Backing the Boys' in the subject line before Wednesday, May 20.
The OLSC have also provided their own unique 'Guide to Edinburgh' for travelling fans - click here for more.
